Kubera, son of Vishrava was gifted an aircraft to visit Shiva temples across the country in recognition of his devotion to Lord Shiva. While he was flying near the river Cauvery Kubera was surprised to see a deer, tiger, cow, elephant, snake and rat drinking water near an Ilandhai tree on the river bank without enmity, to answer his wonder Kubera heard a voice from the sky saying it was a place where vedas visited, inhabited by gandharvas and advised him to worship the shivalingam under the iilanadhi tree. The temples Ilandhai tree gives fruit on all season which was used for everyday puja even today. During the period of Chera Chola and Pandya's there was a cave connection existed between Chidambaram and Sangameshwarar temple and puja's are performed at same time in both temples. The cow behind the Vishnu statue remains the harmony between Saivism and Vaishnavism. It was said from generations that every inch under the temple has one shivalingam. In the year 1804, William Karo, a British Collector of Coimbatore district, visited Bhavani, camping in the Travellers' Bungalow. One night, when he was asleep, a small girl woke him up and got him out of the Bungalow. Once they were out, the Bungalow collapsed. Shocked by this incident, the Collector turned to thank the girl but to find, she wasn't there. The next day, the priest on duty informed him that it was Bhavani Vedanaayaki Amman, who saved his life. He bore three holes in the temple wall exactly opposite to Vedanaayaki Amman shrine and torched these holes to pray the goddess. He offered a gold plate to the goddess with his signature dated 11/01/1804. The holes and the gold plate are present even now and are taken care with caution.
